The Environmental Seismic Intensity scale (ESI 2007) [1] is a seismic scale used for measuring the intensity of an earthquake on the basis of the effects of the earthquake on the natural environment (Earthquake Environmental Effects).
Earthquake environmental effects are divided into two main types: Coseismic surface faulting induced by the 1915 Fucino, Central Italy, earthquake. Primary effects: which are the surface expression of the seismogenic source (e.g., surface faulting), normally observed for crustal earthquakes above a given magnitude threshold (typically M w =5.5 ...

The Modified Mercalli intensity scale (MM, MMI, or MCS) measures the effects of an earthquake at a given location. This is in contrast with the seismic magnitude usually reported for an earthquake. Magnitude scales measure the inherent force or strength of an earthquake – an event occurring at greater or lesser depth. (The "M w" scale is ...
Where an earthquake is not recorded on seismographs an isoseismal map showing the intensities felt at different areas can be used to estimate the location and magnitude of the quake. [1] Such maps are also useful for estimating the shaking intensity, and thereby the likely level of damage, to be expected from a future earthquake of similar ...
“It is also possible that earthquakes can increase the stress at the continuation of the faults or nearby faults, which may trigger other earthquakes.” Does climate change affect seismic activity?
No effect on objects. No damage to buildings. II. Hardly perceptible: Felt only by individuals at rest. No effect on objects. No damage to buildings. III. Weak: Felt indoors by a few. Hanging objects swing slightly. No damage to buildings. IV. Largely observed: Felt indoors by many and felt outdoors only by very few. A few people are awakened ...
The JMA scale is expressed in levels of seismic intensity from 0 to 7 in a manner similar to that of the Mercalli intensity scale, which is not commonly used in Japan.The JMA uses seismic intensity meters to automatically calculate ground acceleration in real-time, reporting intensities based on measurements from observation points.
